Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Subjective sleep efficiency as measured by a sleep log. The sleep log will be recorded by the participants during the 6-week treatment period. The sleep log has several outcome measures: time in bed (TIB), total sleep time (TST), sleep onset latency (SOL), sleep efficiency (SE), wake after sleep onset (WASO) and number of awakenings (AWAK). 2. Sleep quality measured by the Pittsburgh Sleep Quality Index (PSQI) at timepoints T0, T1, T2, T3 and T4 Timepoints: T0 = Day of clinical intake T1 = 4th week of treatment T2 = 6th week of treatment, before randomisation T3 = At the end of sleep training T4 = 2 months after the sleep training | — |
Secondary
| Measure | Time frame |
|---|---|
| Vigilance during the day as measured by the Sustained Attention to Response Task (SART) at T1, T2, T3 and T4. SART will be carried out once a week during the period between T2 and T3. Tertiary outcome measures: 1. Severity of dependency on drugs/ alcohol measured by the Composite International Diagnostic Interview - Substance Abuse Module (CIDI-SAM) at T0 and T4 2. Addiction measured using the addiction scales of the Addiction Severity Index (ASI) at T0 and T4 3. Presence of any psychiatric disorder assessed by the Mini International Neuropsychiatric Interview (MINI) 4. Presence of sleep disorders assessed by the SLEEP-50 at T0, T1, T2, T3 and T4 5. Symptom assessment by the Symptom Check List (SCL-90) at T0, T1, T2, T3 and T4 6. Quality of life assessed by the EQ-5D at T0, T1, T2, T3 and T4 7. Actigraphy at T1, T2, T3 and T4. The actigraph registers movements of the right arm in right handed subjects for 48 hours or more. 8. Go/No-Go response-inhibition task (T1) Timepoints: T0 = Day of clinical intake T1 = 4th week of treatment T2 = 6th week of treatment, before randomisation T3 = At the end of sleep training T4 = 2 months after the sleep training | — |
